[Emby Hardware Acceleration working on j5005 with tweak]

The instructions here enabled hardware decoding on my j5005 board (UHD Graphics 605/Gemini Lake) but encoding produced garbled output.

 

I assumed it had something to do with Unraid or the 4.19 kernel but apparently not - it's solved by forcing Emby to use the container's i965_drv_video.so instead of iHD_drv_video.so.

 

NOTE 1: As of Emby 4.6.* which includes an iHD driver with fixes for Gemini Lake it's no longer necessary to disable iHD, so I've struck through the instructions below.

 

NOTE 2: if you're getting video-related freezes with unRAID 6.9 as I was - adding a dummy HDMI plug to my headless setup and updating Syslinux configuration as below seems to solve it:

label Unraid OS
  menu default
  kernel /bzimage
  append initrd=/bzroot intel_iommu=on,igfx_off

 

Here's how to do that:

 

# Launch an EmbyServer shell:

docker exec -it EmbyServer /bin/sh

# Inside the shell disable iHD_drv_video.so

cd lib/dri/
mv iHD_drv_video.so iHD_drv_video.so.disabled

 

# Restart EmbyServer

 

Now both hardware decode and encode should work.

 

NOTE: You must add intel_iommu=igfx_off to your syslinux.cfg (see this post for details)

NOTE: I'm using the official EmbyServer release in Community Apps
